MACHINE FOR WINDING YARN.

SPECIFICATION forming part of -Letters Patent No. 756,014, dated March 29, 1904. Application filed July 19,1902. Serial No. 116,272. (No model.)

compression-roller having a gudgeon at each end, said gudgeons being journaled in boxes which are secured to slides fitted to the frame, thus permitting the compression-roller to revolve freely without wabbling in its boxes. The compression-roller sustained in this way will be raised gradually as the spool fills with yarn, and it maybe retained at all times in exact working position. The boxes containing the gudgeons of the compression-rollercan also be mechanically lifted. at any time during the process of winding and also at the completion of winding. The pressure on the compression -roller through the boxes and gudgeons at the ends thereof may be increased as desired Without undue wear through the addition of weights arranged at the upper ends of the slides carrying the boxes.

Heretofore compression-rollers have been weighted upon their circumference, andit has been found that the circumference wears unevenly, thus causing the rollers to act unevenly, andit will be obvious that the heavier the weight the greater the wear on that class of rollers.

I prefer to use aplain-surfaced compre s-.

sion-roller; but this invention is not limited in all instances to the use of such aroller only, as I believe that I am the first to sustain a compression-roller by end journals in the manner described.

\ Another feature of invention herein contained relates to novel movable bearingsfor sustaining the journals of thespools on which the yarn is being wound. These bearings serve to sustain the spool not only during the winding operation, but also while the operator severe the thread from the full spool preparatory to removing the spool from the machine and also while putting a new spool in position to have the yarn attached to it.

Another feature of invention relates to means for supporting and moving the compression-roller bearing on the yarn being wound and for retaining said roller in an inoperative position while changing spools.

Another feature relates to novel means for providing for varying the stroke of the traverse-guide.

Another feature relates to means for changing at will the relative direction of reciprocation of the front guide and the yarn-guides that lead the yarn into the machine. I Figure 1 is a perspective view. of a winding-machine containing my improvements in one of the. best forms now known to me. Fig. 2 is a left-hand end view thereof with parts broken away. Fig. 3 is a right-hand end view of the machine shown in Fig. 1. Fig. 41s a rear elevation looking in the direction of the arrow, Fig. 2, partially broken out to shorten the drawing, some of the parts being omitted. Fig. 5 is an enlarged detail showing part of the machine with the stop-' motion Wires elevated, the machine being covered, preferably, with some rough materialto aid in rotating the spool.

Theshaft a is provided at one end with a fast pulley A and a loose pulley A said pulleys being supposed to be driven by a belt under the control of a belt-shipper A, connected with a shipper-bar A, sustained in suitable guides of the framework and being adapted to be moved, as will be described, to stop or start the drum.

The drum A is adapted to sustain and rotate a spool B, having suitable heads'B, that embrace the ends of the drum. The journals 6 of the spool enter slots .7) of peculiar bearings B having extended therefrom a rest 6 said bearing being shaped to surround loosely 'and slide on a movable guideway 12 shown as forming part of a casting b, bifurcated at its lower end and bored to surround the shaft a. Each casting b has an ear 6 (see Figs. 2 and 3,) with which is connected loosely a slotted link 6, in turn jointed to the framework. The link constitutes a stop to limit the extent of the outward turning or movement of the guideway about the shaft a or from the position shown in Fig. 2 into the position shown in Fig. 1.

The bearings B are movable freely on the guideway and slide upwardly thereon during the operation of winding yarn on the spool. The bearings occupy the position Fig. 1 only when the wound spool is to be removed from the machine and while the journals of a new spool are being put in place to enter the bearings.

When the machine is without a spool, the bearings B occupy an abnormally low position. In this abnormally low position the rests b extend just far enough to permit the operator to place the journals of the spool over the rests, and then by slightly lifting the bearings from their abnormal position the spool-journals may be slid farther along over the said rests until said journals come in line with the slots 1), when the bearings will be dropped, causing them to be suspended on the spool-journals. This done, the operator by hand winds the ends of the yarns about the body of the spool and then pushes against the spool, moving it and the guideways Z2 in the arc of a circle about the shaft at until suitable locking devices 0, carried by the upper ends of said guideways and actuated, preferably, by suitable springs c, engage a suitable projection 0 attached to the framework. The locking devices secure the guideways for the hearings in their operative positions throughout the winding of the yarn on the spool, and during this operation the bearings B slide upwardly on the guideways until the spool is fully wound.

When a spool is to be removed, as in Fig.

1, the operator will depress the outer ends of the locking devices and disengage them from the projections c and then pulling outwardly on the spool thus turn the guideways forwardly. In this forward position the operator has free access to the yarn between the traverse-guide, to be described, and the spool to cut the yarn preparatory to removing the wound spool, and after the cut ends have been caught together in usual manner the oper ator by handmay lift one bearing B after the other and disengage the slots 6 thereof from the journals 6 of the spool, letting the journals pass over the rests b and finally leave the machine. This operation greatly lessens the labor of the operator, who has heretofore commonly supported the spool by one knee while severing the threads and getting ready to move a Wound spool.

To insure a close and compact winding of the yarns on the spool, I employ a compression-roller C, each end of which is chambered, as represented at 0 Figs. 2 and 4, so that the journals 0* (see Fig. 4) of said roller occupy a position in said chamber, the ends of the journals not projecting beyond the outer end of the roller.

The journals 0 of the compression-roller enter suitable bearings C, shown as offset or shaped at their lower ends to enter the chambers c at opposite ends of the compression-roller. These bearings are each fixed to the lower end of suitable slide-rods C free to be moved longitudinally in guides C represented as securing to or forming part of the framework. Each slide-rod is herein supposed to be provided with rack-teeth 2. (See Figs. 2 and 3.)

Each series of teeth is engaged by a pinion 0, fast on a shaft C, extended across the framework and provided with a suitable handle by which to rotate the shaft G whenever it is desired to raise the compressionroller by hand into its inoperative position, as when the wound spool is to be removed.

The compression-roller must be locked in its inoperative position during the removal of the spool, and to provide for this said shaft has fixed to it a ratchet-wheel o that may be engaged by a tooth of a hand-lever 0, mounted to turn on a suitable tie-rod 0 In practice the upper ends of the slide-bars will be provided with a series of weights D- any desired number, that depending upon the degree of compression desired while winding the yarn.

It will be noticed in winding yarn on the spool that the ends of the compression-roller substantially fit the inner sides of the spoolheads and that the periphery of the compression-roll bears on substantially all the threads coming onto the spool to be wound.

Prior to my invention I am not aware that the bearings for a spool have ever been permitted to slide vertically during the winding operation on guideways that might be moved or tipped in such manner as to permit the Wound spool to be moved aside from the position occupied by it during the winding, enabling the bearings to sustain the spool mechanically while the operator severs the threads between the traverse-guide and the spool, and this feature I desire to claim broadly irrespective of the construction of the devices employed to secure this result, and so, also, I am not aware that a compression-roller has ever been chambered at its ends that the bear-- ings sustaining the shaft of the compressionroller might be contained within a chamber at the ends of said roller.

The bearings C, sustaining the journals of the compression-roller, as shown in Fig. 4, have lips 0 that embrace each a ledge 00 of the framework, and said bearings are thus always maintained in a defined path, and it is obvious that any strain that might tend to move the axis of rotation of the compressionroll out of line with or away from its operative position with relation to the driver and spool is obviated.

The shaft a has at one end a worm D, that engages a worm-toothed gear D fast on and rotates a cam-shaft D sustained in suitable bearings supported by the framework. This shaft has a suitable cam D for actuating the traverse mechanism to be described.

The shaft D has a second cam D shaped the same as cam D*, that acts upon a suitable arm 03 of a rock-shaft, sustained in a suitable bearing d on the framework and having a second arm d forked at its upper end and provided with pins that enter a suitable annular groove in a collar d see Fig. 8,) secured to a circular block fast to one end of the front thread-guide d by a suitable screw, the movement of said lever reciprocating said guide. This thread guide has suitable holes (see Fig. 8) through which the yarns led from any suitable guides, bobbins, or spools may pass on their way over the front sustainingroll 6Z7. v

The front thread-guide (see Fig. 8) is represented as entering loosely correspondinglyshaped-holes in two like circular guide-blocks 7, inclosed by bearings 8, supported by the framework. The blocks may be secured in any adjusted position desired by means of a set-screw 9 engaging the circular exterior of the block, and by rotating the blocks more or less in the bearings 8 the guiding-holes of the thread-guide 616 may be placed at any desired angle, according to the direction from which the yarns to be Wound approach said guide.

A'suitable'spring 1O acts normally to keep the arm 0Z against the cam D The thread-guide 6, having suitable holes,

preferably slotted, into which the yarns to be wound are laid one in each hole, the yarn going from thence onto the spool, is guided in suitable blocks 6', secured-by suitable setscrews e in suitable bearings 10 of the frame, that said blocks may be turned in order to place the guide 6 in just the desired position.

The left-hand end of the guide (see Fig. 6) has connected loosely with it in suitable manner the hub of an arm (2 said hub being disposed between two suitable nuts, as e 6, adapted to be turned on a suitable threaded part of said guide in order to adjust the position of the arm 6 with relation to the end of I have provided the lower end of the arm with a stud 6 over which fits ahole at the end of a link a, (see Figs. t and 6,) in turn jointed at e to an arm '6 secured to a rockshaft 6, held in a suitable bearing 69X of the framework, said rock-shaft having connected with it a second arm 6 represented as slotted to receive a pin a, with which is connected a second link 6. The opposite end of the link 6 is jointed by a pin c with a vertically-movable collar a, free to be slid vertically on a guide-rod e rising from a lever 6 having its fulcrum at e on a suitable bracket 6 connected with the framework.

The upper end of the guide-rod 6 has pinned tolit at e a block f, that receives a screw f, having at its upper end a hand-wheel f said screw being mounted loosely in said block f, so that it may be rotated and not slid therein. The threads of the screw f engage suitable threads of the block 6 so that by rotating the screw the block 6 may be raised or lowered on the guide-rod e to secure a longer or shorter stroke. or throw of the traverse-bar or to alter the throw in any-desired manner of said guide. This adjustment or change of throw may be made by turning the hand-wheel f 2 without stopping the machine, and the adjustment having been efiected a suitable checknut f 3 may be actuated to restrain any accidental rotation of the screw in the block 9 The lower end of the lever 6 has a toe 12, that is acted upon by the cam D, a spring 62X (see Fig. 4) causing said toe to contact with said cam. I believe that I am the first to provide any means whatever for adjusting automatically' the extent of throw of the traverse-guide without stopping the machine, and I desire to claim this feature broadly irrespective of the particular construction of machine illustrated for effecting such result.

The yarns to be Wound are supposed to be passed through suitable holes in the front guide d and thence around and under the front guide-roll d thence up and over the guide-roll (Z and thence to and through suitable drop-wires l3, and thence over a roller suitably mounted upon the frame 14, and thence through the holes in the thread-guide, and from there to the spool.

Fig. 5 shows means employed for sustaining the drop-wires and part of their actuating means, and referring to said figure it will be said guide, this adjustment being desirable to seen that each drop-wire is pivoted on a foot h, said feet being inserted in a guideway of a suitable bar 12,, the feet being retained in said guideway by a plate b secured to said bar. The feet are inserted loosely in the guideway of the bar, so that they may move laterally as necessity requires to adapt themselves to the line of the yarn. The bar it is extended upwardly to act as a stop to arrest the dropwires sustained by the threads in such a position that in case a yarn breaks the drop-wire will always fall toward the front of the machine, as represented by dotted lines, Fig. 5.

When a thread breaks, the drop-wire is arrested in its down position by means of a suitable bar 71., connected with an arm k fast on a rock-shaft h, and in this position the end of the drop-wire is met by a moving bar If, connected with suitable arms h, carried by a rock-shaft if, said bar being arrested by a drop-wire in its abnormal position and effecting, as will be described, the movement of the shipping mechanism to stop the machine.

The rock-shaft h has fast on it an elbowlever h provided at one end with a pin 12, that during the operation of the machine and while all the yarns are whole is engaged by a notch of a lever i23 pivoted on a stud [2/ carried by an arm h, secured to a short rockshaft It, sustained at but one side of the framework, the opposite end of said rockshaft (see Fig. 2) having connected with it an arm h having jointed to its upper end by a suitable pin one end of an eccentric-strap it, the opposite end of said strap embracing an eccentric [L18 on the drum-shaft a.

The arm m of the elbow-lever [L10 is provided with an adjustable weight 177. having a tendency to keep the pin 12 in engagement with the notch of the bar h as the bar [L12 is moved to and fro by the eccentric-strap it", and so long as the threads are unbroken the arm 7& and the bar 72/ will have a uniform movement; but whenever a drop-wire falls into its abnormal position and the movement of the bar 72 is arrested by a drop-wire the arm It is released from the pin 12 during the movement of the bar h" to the left, viewing Fig. 5, by the eccentric h letting the arm h drop and permitting a dog m thereon to engage a similar dog m carried by an elbowlever m having its pivot at m thus turning said lever in the direction of the arrow 18 thereon, Fig. 5, causing the free end of said lever to retire from a notch 20 in an auxiliary shipper-bar m parallel with the main shipper-bar A and'thereafter a spring m (see Fig. 4,) connected with a rocking lever m; pivoted at m and slotted at its upper end to engage a pin projeeting from a block m connected with said auxiliary shipper-bar to slide said shipper-bar to the left, viewing Fig. 4, causing the end of said bar m beyond its guide m" to abut a blockm, connected with the main shipper-bar and move the latter to the left, transferring the belt from the fast onto the loose pulley,

As the lever mi is moved by the spring m it acts through a link a, suitably connected with one end of the arm h, mounted on the rock-shaft h and heretofore described, to turn said rock-shaft and arm A upwardly in the direction of the arrow, (shown to the right of it in Fig. 5,) causing the bar h to return the drop-wire into its position to receive amended or pieced thread.

The floor sustainin able bearings, as 72, see Fig. 1,) to sustain a treadle-shaftn, provided, as represented,with two treadles n n". The inner end of the treadle-shaft has an arm n that is slotted and has connected with it adjustably a link a in turn jointed at one end to the lower end of a lever 11", having its fulcrum at n. The upper end of said lever is jointed to a link a", in turn jointed to a block a, fastened to the main shipper-bar.

If the driving-belt is on the loose pulley, the operator may start the machine by putting her foot on the treadle a, sliding the main shipper-bar to the right and putting the belt on the fast pulley.

As the main shipper-bar is moved to the right to transfer the driving-belt from the loose to the fast pulley the dog m meets the end of the auxiliary shipper-bar m and slides the same to the right, enabling the heavier right-hand end of the lever m to enter a notch in said bar m thus locking the shipper in its operative position, (see Fig. 5,) said lever remaining in engagement with said notch until said lever is again moved after the falling of a drop-wire, as before described.

By the branch n of the treadle the machine may be stopped, and it may be restarted by the branch n of the treadle independent of the stop-motion after once set, and this may be done whenever desired independent of the stop-motion.

In some winding-machines the compressionroll is provided with a series of annular grooves through which the yarn being wound upon the spool is led, but in such construction it will be noticed that the roller does not act directly by its weight or pressure upon the yarn to lay the same tightly onto the spool, and it will also be noticed that the yarn comes upon the spool at'the upper side thereof. I consider it of great'advantage in closely and solidly winding the yarn upon the spool that the compression-roller act directly upon each yarn as it is being wound upon the spool and that the yarn. being wound contacts with the drum at the under side of the spool, and when the annular grooves-in the compression-roller are not used I deem it of importance to locate a thread-guide, as e, just behind the spool on which the yarn is to be wound, said threadthe machine has suitguide delivering the thread immediately at the point of contact between the drum and the wound yarn of the spool.

It will be noticed that when the thread is guided by grooves in the compression-roll that it is impossible to control the thread and wind the spool-heads.
